iinink"n"U[)U-(l ciiriXMit, \v;is a constant anti respectable stream. 

 Both Irom the severity of tlie cokl and from its continuoi:siie.s.s, 

 the winter was extremely rigorous ; the mercury ranged between 

 20° and 25° with unpleasant frecjuency, and once fell so low as 

 10°. 



Under circumstances so diflerent, it is to be expected that there 

 should be a diRerence in the results of the work of the two sea- 

 sons. As a matter of fact, variation in manner of occurrence is 

 apparent in the case of almost cAcry species. The aggregate of 

 individuals was much greater in 1SS3, the increase in numbers 

 being, except in a few cases, proportionate. The most promi- 

 nent exceptions were Zonotrichla gambeli intermedia^ Den- 

 drceca coronata^ Dendroeca chrysopa}-ia (three specimens), 

 Helminthophila celata. Eremophila alpestris ch^'ysolcetna^ 

 AntJms ludovicianits and Sialia arctica^ which were decidedly 

 less numerous ; and Certhia fatiiiliaris rzifa, Salpinctes 

 obsoletus^ JSJ^eocorys spragiiii^ Dendrceca blackburnce^ Vireo 

 atricapiUtis^ Sinrus nwtaciUa^ Stelgidopteryx serripentiis^ 

 Rhyncophancs niaccozvni, Spizella breweri^ Calainospiza 

 bicolo/\ Podasocys montaiuis^ and Plotus anhinga^ of which 

 nothing was seen. 



Alelospiza li/icolni and Chondestes grammica were abundant 

 \vinter residents in 1^83 ; in 1S80 the former figured only as a 

 migrant, the latter as a migrant occasionally occurring in winter. 



The following additional species and varieties were detected in 

 1883 :- 



1. Hylocichla unalascae pallasi (C(7(5.) Ridg. Hermit Thrush. — A 

 specimen taken, March 16, from a small flock of apparently the same race. 

 Examples approaching var. audubo?ii w&vq. taken at intervals.* 



2. Sialia mexicana Sivainsoii. Californian Bluebird. — On Janu- 

 ary 28, half-a-dozen Bluebirds appeared in a field adjoining the hotel. 

 Their restlessness and peculiar behavior led me to sally out in pursuit of 

 a specimen, which I secured with some difiicultj. It proved to be a female 

 of the present species. The rest of the birds flew away, at the report of 

 my gun, and nothing further was seen of their kind until the afternoon of 

 March i. At this date I was collecting among the Balcones Hills, a few 

 miles from Boerne, in a section of country covered with a sparse growth 

 of live-oak. My attention being attracted by a faint twittering over my 

 head, I looked upward and beheld eight or ten Bluebirds descending al- 

 most perpendicularly, as if from a great height. As before, they proved 

 restless and shy. and, after a single discharge of my gun. which secured 

 a handsome male, they left the vicinity.
